"So whether it's photos from your recent camping trip, video footage from your brother's wedding, or a presentation to your boss, all your stuff is easy to find and easy to share with Drive and Gmail," the post reads.

The move is part of an ongoing effort by Google to synchronize its various services, from Gmail to social network Google Plus to the Android mobile operating system. The ability to sync with Gmail offers Google a built-in edge over standalone cloud storage tools like Dropbox.

"Should services like Dropbox be concerned? Sort of," wrote Ricardo Bilton of VentureBeat. "As the move shows, Google's core strength is in its ability to connect and integrate its various services -- even the unpopular ones -- into one cohesive product. This gives Drive a clear edge over competing standalone cloud services, so expect Google to leverage it as much as possible."

The file-sharing feature will be rolled out over the next few days, according to Google. Users must have opted in to Gmail's "Compose" tool in order to use it.
